Establishment
1-2 yearsYoung tree focuses on root and branch development rather than fruiting. Slow vertical and lateral growth.
Remove flower buds in first 1-2 years to direct energy to structure. Stake for wind protection. Water regularly. Prune to establish strong scaffold branches.
Vegetative Growth
2-4 yearsTree develops sturdy framework with primary and secondary branches. Canopy becomes fuller and more defined.
Continue pruning to maintain open center or spindle form. Thin crowded branches for light penetration. Fertilize moderately in spring.
Flowering
2-3 weeksWhite-pink blossoms appear in spring (late April-May depending on zone), clustered on fruiting spurs. Flowers are self-fertile but benefit from cross-pollination.
Protect from late frosts if possible. Allow some flowers to set; thin later for fruit size. Avoid heavy pruning during bloom. Trees typically start substantial flowering by year 3-4.
Fruit Development & Growth
8-12 weeksSmall green fruits develop and enlarge throughout summer. Apples gradually develop red coloring as they mature.
Thin fruits to 4-6 inches apart to encourage large fruit size and prevent branch breakage. Water consistently during dry periods. Monitor for pest/disease issues. Support heavy branches with props if needed.
Ripening & Harvest
2-4 weeksApples reach full size with deep red color, developing characteristic waxy bloom. Flavor and sweetness peak. Ready to harvest in late August through September.
Check ripeness by gentle twist and lift of fruit. Stop nitrogen fertilizing 6-8 weeks before expected harvest. Reduce watering slightly to concentrate sugars. Harvest carefully to avoid bruising.

Common Pests
-
Remove fallen fruit, use pheromone traps, apply kaolin clay spray, thin fruit for air circulation
-
Prune to improve air flow, monitor with sticky traps, apply insecticide if needed at petal fall
-
Dormant oil spray in late winter, horticultural oil in growing season, prune heavily infested branches
-
Increase humidity through overhead watering, use miticide if severe, encourage predatory insects
-
Hand-pick in early morning, use pheromone traps away from tree, apply neem oil if populations high

Harvest Tips
Magna apples typically reach harvest readiness in late August through early September. Pick when apples have developed full red color and give slightly to gentle pressure. Use the gentle-lift-and-twist method to avoid bruising. Harvest in the morning when fruits are cool. Can be refrigerated for 3-4 months. Do not harvest all at once; a second picking 7-10 days later often improves quality of remaining fruits.
